turned serrated inneredge 36 is removably The meat or other material tobe cut is adapted to be placed upon this tray.

The carriage is provided with a pair of arms 37 extending upwardlyeither side of lthe plate 32 and pivotally mounted in the upper ends ofthese arms above the plate are the bell crank arms 38, the inwardly extending' members of which are providedwith pivotally serrated grippermembers 39.

The outer and upwardly extending members of thebell cranks are connectedAby a link 40 and a lever 41, the link being connected to the leverintermediate of `its length. When the lever is thrown inwardly both o fthe bell crank members swing outwardly thus throwing the inner memberscarrying the grippers away from the table to allow the placing of themeat to'be cut.

Thel bell crank members are provided with spiral springs 42 which tendto force the gripper membersdownwardly to hold the meat securely inplace.

The carriage is provided with a downwardly extending arm 43 inwhich ispivotally supported an arm 44 carrying a pin 45 projecting downwardly toengage a spirally threadedfshaft 46 extending longitudinally thereunder.The rotation of this shaft moves the carriage forwardy as the knifemoves clear of the material to be cut. The shaft is operated by a pairof clutch memsection in Figure V7.

The form of clutch shown is of the ball type, the spring held balls'49engaging the cone 50vwhich is' Vsecured to the shaft. The

' clutch 47 is adapted to grip and hold the shaft from backwardrotation, it being held in a stationary position by the rod 51illustrated in'Figure 3 or the rod 52 illustrated in Figure 6. Thisclutch member is provided with a pin 53 extending toward the member 48and the member 48 is provided with a pin 54 adapted to engage the pin53.

In the mechanism illustrated inFigure 3y l'the clutch 48. has connectedto its outer side a bar 55 which extends upwardly and is pivotallyconnected to a bar 56 extending rearwardly and pivoted .to the casing 2.

The arm 14 is provided with a pin 57 on.`

its inward side` which is adapted to engage the underside of the bar 56t o lift it following the backward swing of the knife arm and on beinglifted the movement is transmitted through the rod 55 to turn the clutch48 to grip the shaft and turn it, thus through the worm and pinconstruction described, advancing the carriage.

The degree of advance is regulated by the rods 51 and 52 to bringthe pin53 on the clutch v47 vinto such a position as to engage the pin 54 tolimit the return movement of the clutch 48. This adjustment can beregulated so that the feed shaft may be turned a very slight amount inorderto produce a very thin slicing or may be turned to any degree toproduce an extra heavyV slice. Y

l.The adjustment of the rod 51 is eected through a thumb lnut 58 but amore deinite karrangement of graduation may be effected by means of aquadrant lever 59 as illustrated in Figure 6. l

' In the construction shown in Figure 6 the clutch 48 is operated by alink 60 connected to an arm 61 pivotally mounted within the casing andengaged by a roller. pin 62 mounted on the spur gear 8. The pin beingmounted on the spur gear will operate with a smoother action than willthe mechanism operated by the pin on the swinging arm, which may be moredesirable, and will not convey the shock incident to the othertransmission.

In the operation of this machine the meat to be sliced is placed uponthe tray 34 and the gripping levers are thrown down, the springs holdingthe gripper members in flexible contact therewith. They meat projects'beyond the grippers and beyond the tray and slides on the longitudinallycorrugated plate 32 and is fed up to the knife.

The rotation of the hand wheel then revolves the knife through the trainof gears described and as the spur gear 8 revolves the roller pincarried' therebyoperates the knife carrying arm to swing forwardly andas the carriage is Varranged considerably below the axis of the knife,the cutting will be effected mostly, if not entirely, below the centreand as the knife swings forwardly it also swings downwardly, thus makinga downward cut which is most desirable as itV cuts toward the solidsupport of the carriage aid thus avoids cutting slices thick on one s1e. Y

The knife feeds forwardly at a moderate rate of speed as the operatingpin travels around the outer portion of the orbit of the spur' gear andfollowing the completion of the forward movement, the pin moves inwardlytoward the pivot and thus swings the knife back with an acceleratedmovefrom said base, a rotatable knife and means for rotatmg the knife,of an arm rigidly connected with said pivotal knife arm, a wheelVlongitudinal slot therein, a gear wheel 4operating the knife rotatingmeans and arranged in eccentric relation to the pivot of the knife arm,a pin arranged upon said gear engaging the longitudinal slot in saidslotted arm, a casing enclosing said gear and slotted arm arranged atone end of said base,A
